Benign Hat Pressure Syndrome. 

Also known as BHPS.

A harmless condition in which the catalyst event is inadvertently bought about by the victim wearing a hat for novelty purposes, while they are not generally accustomed to wearing one.
They do this under marijuana inebriation.

The marijuana ingestion causes vagueness and temporary loss of short term memory in the victim, and the irregular use of the hat becomes forgotten.

The victim senses the anomalous pressure caused by the hat, and perceives it to be something akin to a "headache", an imbalance, or loss in equilibrium.

For treatment of BHPS, identification of the cause (see: hat) and removal will result in alleviation of the symptoms.

This results in a return to relative normalcy, and increased feelings of joy in the (now) former victim.

Most often, identification will be made by a secondary party - Hat removal procedures can be performed by either of the aforementioned, a nigh-immediate improvement will be noted thereafter.

The syndrome has been known to recur at times of subsequent marijuana usage.

He thought there was something wrong.

There wasn't.

It was merely a case of Benign Hat Pressure Syndrome.

Removal Procedure began immediately upon identification.
